Title: Game machine
Inventor: SATO REO
IPC: A63F7/02
Filed: 2020-03-17
Abstract: To provide a technique for performing in a seamless state, switching of music.SOLUTION: A game machine is configured so that, with selection and determination of music by an operation performed by a player, as a trigger (time t2), fade out of music 1 being played back at a track 1, and after passage of 15 frames (time t3), fade in of music selected at a track 2, is started. The fade in and the fade out are performed by sparing 45 frames, and in a section (time t3 to t5) where both pieces of music are cross faded, determination SE is played back in an overlapped state to both pieces of music. By using two tracks in switching of the music, the pieces of music can be output from a speaker in a state of overlapping respective pieces of music before and after switching, so that, without generating a silent section, switching can be performed in a seamless state by a mode in which pieces of music can be heard naturally. In addition, the determination SE is overlapped and played back, so that, even a beginning part of the determined music is silent, generation of a section which sounds silent, can be avoided.SELECTED DRAWING: Figure 55
